Urgent help: How to add thickness to "pipe" command

Hi hope all is well, just a quick urgent question. I'm a beginner and working on this weave model and unlike the "pipe" command in Rhino where you can choose to add thickness to the curve, I can't seem to find a way/don't know how to do so in grasshopper.
Any suggestions? Many thanks in advance.

mmm You want it to be colsed at the end?

to do so, just change the last input (look at the hint window)

If you meant closed brep as a pipe, you should make two pipe components, extract ending curves and, for example, loft them. Then joun all surfaces to one brep

Create two capped pipes and then use solid difference.

With the right Data Management this can be applied to multiple pipes

I guess the real answer is: see surface->freeform->pipe :)

your real answer is for a fictitious question :)

"pipe" command in Rhino where you can choose to add thickness to the curve

There is no mechanism built into [Pipe] that allows you to specify a thickness. So a process whereby you create a either a section to sweep/loft or a solid difference approach or I suppose a surface offset with a means to cap the ends is probably your only options.

Think of it in simple terms... "adding thickness to a curve" is giving it a non-zero radius. In other words: piping it.

yeah, exepth that He asked how to add thickness to a pipe, not to a curve :-)

Sorry. I totally missed that option in the command. In the german localisation it says "Grob" which translates to coarse or rough instead of "Thick". So the thickness made no sense to me.

Hey thanks a lot guys!! I tried doubling the capped pipe and then using solid difference and that seem to work well!

I beg to differ in regards to my question being fictitious as it's not (to my mind).. in the screenshot below I've highlighted in green the bit in Rhino which lets you choose to add thickness by choosing Yes, which results in the bottom left pipe :)

Also, I'm a She, not He if that matters.

More importantly, many many thanks!!! You've saved me time&headache and added more vocab/sense to my grasshopper language!

I merely meant that Hannes had not read the real question.

This approach will work, but just expect it to slow down if you have hundreds or thousands of members due to the solid difference. Better to extrude/sweep, and join planar end faces (which is the approach embedded in StructDrawRhino if you're happy with a plugin solution. The image blow shows an universal beam component, there's a similar circular hollow section generator).
